Answer:
v = 7121.3 m/s
Explanation:
As we know that the centripetal force for the space shuttle is due to gravitational force of earth due to which it will rotate in circular path with constant speed
so here we will have
here we know that
r = orbital radius = 6370 km + 1482 km
also we know that
now we will have
2.3275862×10¹²km/s fast is sirius moving in km/s.
<h3>Briefing:</h3>Hydrogen has a spectral line at = 116nm=116×10⁻⁹m
Line is observed at = 107 nm=107×10⁻⁹m
Now, from the Hubble's law
V=×C
Where,
v is the velocity
Δλ = Change in wavelength = 116 - 107= 9nm=9×10⁻⁹m
λ = Actual wavelength=116nm=116×10⁻⁹m
C is the speed of the light=3×10⁸m/s
on substituting the respective values, we get
V=(9/116)×3×10⁸=23275862.069×10⁵m/s
V=2.3275862×10¹²km/s.
<h3>What is the wavelength?</h3>A waveform signal's wavelength, which is the distance between two identical locations (adjacent crests) in the succeeding cycles, determines whether it is sent through space or via a wire. Typically, in wireless systems, this length is specified in meters (m), centimeters (cm), or millimeters (mm).
